Stamnesia 

Short for Stoner Amnesia
(Pronounced, Stam-nees-ee-yer)
To loose any sense of rememberance whilst stoned.

To think of something you must do, but then completetly forget about it because you are stoned, and then remember that you just remembered you must do something, but you cant quite remember what it is, and therefore, leaves you thinking about what that thing is for a good hour and a half untill you finally remember what it was in which gives you a huge sense of accomplishment.

Can cause stoners to freak out or become very light headed.

Stoner 1: "Aww man i just remembered something"
Stoner 2: "Whats that?"

Stoner 1: "Aww shit man, i fucking forgot!"
Stoner 2: "Dude, terrible stamnesia"

shopper's amnesia 

A condition relating to being in such a shopped-out state that one forgets her purchases.

1. Person 1: "I got a phone call to pick up a purchase from a store and I honestly don't remember ever putting the layby on!"
Person 2: "Wow, sounds like you've got a case of Shopper's Amnesia."

2. Lisa went to the store and found the hit Drew Barrymore film Ever After in the bargain bin for only $9.89. Lisa loves Drew Barrymore. Upon arriving home she attempted to put the new DVD into her alphabetically categorised collection, only to discover that she already owned a special edition copy of said film. Lisa blamed this unnecessary purchase on momentary Shopper's Amnesia.
